Analisa Penggunaan Abu Vulkanik Gunung Sinabung Sebagai Bahan Filler pada Campuran Panas AC-WC Menggunakan Aspal Buton

Abstract

Filler is one that serves as a filler material cavities of an asphalt mixture. Kinds of fillers that can be used are: gray stone, lime extinguished, portland cement (PC) etc. A small percentage of the filler to the asphalt mixture, it does not mean do not have a profound effect on the nature or value of Marshall characteristics. An eruption of Mount Sinabung in recent years in the area of Tanah Karo, North Sumatra, leaving plenty of material shed from the eruption. This has caused many volcanic ash that still can not be resolved to the maximum. On the other hand Indonesia has abundant natural resources, one of which is a natural bitumen contained in Buton Island, better known by the name Asbuton. This study tried to examine the volcanic ash from the eruption of Mount Sinabung in its use as a substitute filler in a mixture of AC-WC Asbuton. In this study the manufacture of test specimens (bricket) mixed in hot (hot mix) and refer to the Highways 2010 General Specification Revision 3 Division 6 as well as the Special Spec Mix Heat With 2006. Variation of Asbuton volcanic ash from Mount Sinabung used is equal to, 25%, 50%, 75% and 100% of the filler material contained in the fine aggregates. From the Marshall test result data obtained, the levels of filler that meets all the requirements of Special Spek Heat Mixed By Asbuton 2006 is a volcanic ash filler at a percentage of 50%. Where the value of acquired characteristics marshall has met specifications. stability of 2225 kg, flow was 4.2 mm, MQ amounted to 592, 8 kg / mm, VIM amounted to 4.16% and amounted to 74.83% VFA. It can be concluded that the replacement of filler with Sinabung mountain ash maximum of 50%.
